类名称：Optional
方法名：get

Optional.get介绍

[英]Returns the contained instance, which must be present. If the instance might be absent, use #or(Object) or #orNull instead.

Comparison to java.util.Optional: when the value is absent, this method throws IllegalStateException, whereas the Java 8 counterpart throws NoSuchElementException}.
[中]返回包含的实例，该实例必须存在。如果实例可能不存在，请使用#or（Object）或#orNull。
与java的比较。util。可选：当该值不存在时，该方法抛出IllegalStateException，而Java 8对应的方法抛出NoSuchElementException}。
